PROBLEM TO BE SOLVED: To obtain a nonhalogenated composition for coating excellent in adhesion, water resistance and solvent resistance without using solvents. SOLUTION: This two-part type coating composition is composed of (1) a main ingredient comprising (A) a polyol component and (C) a chain extender and/or (D) a crosskicking agent as necessary and (2) a curing agent comprising (B) an organic polyisocyanate. The polyol component (A) contains a 3-40C aliphatic hydrocarbon in a side chain thereof, is composed of one or more of (A1) a polymeric polyol having 500-10,000 number-average molecular weight and has 5-80 wt.% content of the 3-40C aliphatic hydrocarbon in the side chain in the component (A).
